Controller John Liu admitted that time and money has been wasted on the project.

The city's bloated $2 billion program to revolutionize its 911 system remains stalled - and even a plea to NASA for help has not been answered with rocketlike speed.

Managers at the overbudget and behind-schedule Emergency Communications Transformation Program reached out to NASA for guidance in February - but a deal has still not been reached to have the space scientists monitor the system.

Additionally, construction on a 911 call center in the Bronx remains stagnant - and much of the $95 million authorized to develop its computer network sits unspent, records show.

"Notwithstanding the importance of this system," said city Controller John Liu, "there is unfortunately reason to believe that a huge amount of time and money has been wasted on this project."

Liu's office is auditing the entire undertaking, which is years behind schedule and has seen its costs balloon from $1.3 billion in 2005 to $2 billion today.

In an effort to stabilize the sagging project, the city announced that it was going to hire NASA's Independent Verification and Validation office.

That team, which normally tests telescopes and satellites, was going to troubleshoot software used to dispatch FDNY and NYPD vehicles - but the deal remains unsigned.

The massive 911 project combines the FDNY and NYPD communications systems, but has led to dispatching errors and complaints from the rank and file.

A key component is a backup call center being built on a Bronx flood plain - but the $650 million facility is still little more than a foundation in the ground.

In January, Liu flagged a $286 million contract for the center, saying it allowed Northrop Grumman to bill by the hour - the same situation that led to massive overruns on CityTime.

Two months later, Liu approved a restructured $95 million contract in which payment is granted when tasks are completed. So far, only $3.6 million has been spent, according to the controller's records.
